The moment magnitude scale is better suited for measuring the "sizes" of very large earthquakes and its values are proportional to an earthquake's total energy release, making ... Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the "size," or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.)Two of the most common methods used to measure earthquakes are the Richter scale and the moment magnitude scale. The Mercalli scale also measures the effects of an earthquake at different locations.Intensities a measure of the amount of ground shaking at a given location. Intensity not magnitude measures how about the earthquake is a location. Most common measurement of intensity is a modified Mercalli scale. Mercalli scale. Modified Mercalli is a good qualitative description of intensity in terms of damage levels.

Relation between Magnitude, Energy and Intensity. If the earthquakes would occur at only one, say shallow, focal depth, the maximum seismic intensity at the surface could serve as a rating of the strength of the given earthquake, provided the ground conditions were similar at all observational sites. The Richter scale is a numeric measure of the magnitude of an earthquake. Beno Gutenberg and Charles F. Richter, both of whom were American seismologists in the year 1935, created it. The magnitude of an earthquake is measured by determining the height of the biggest seismic wave shown on a scale by a seismograph.
